The high-resolution 1h nmr spectra and conformations of n-acetyl-α-d-galactopyranosylamine peracetate and 1, 1-bis(acetamido)-l-deoxy-d-glucitol peracetate in aqueous medium
In contrast with the spectra previously measured with lower resolution equipment, the 500-MHz 1H NMR spectra of l, l-bis(acetam1do)-1-deoxy-D-gl ucitol peracetate and N-acetyl-α-D-galactopyranosylamine peracetate in aqueous solution were amenable to full resolution. The former compound shows a “sick...

| Sumario: | In contrast with the spectra previously measured with lower resolution equipment, the 500-MHz 1H NMR spectra of l, l-bis(acetam1do)-1-deoxy-D-gl ucitol peracetate and N-acetyl-α-D-galactopyranosylamine peracetate in aqueous solution were amenable to full resolution. The former compound shows a “sickle” conformation produced by rotation of the C2–C3 bond out of the planar, zigzag arrangement, while the latter has a 4C1conformation. © 1987, Taylor & Francis Group, LLC.
